The In-Chamiel Response of an Electroacoustic Feedback Channel
The in-channel response of an electroacoustic feedback channel has been investigated in detail paying great attention to transient effects, and using both computer simulation and real measurements in several physical models. For positive feedback the effect of parameters including toneburst length, source frequency, and enclosure reflection coefficient has shown the limitations of existing theoretical predictions for the increase of reverberation time. Results for negative feedback differ from other recent work and suggest reverberation time reduction for transient signals by negative feedback is not easily obtainable.
